Some OCD cleanups on some of the perl@ ports.
- Remove dependencies in core
- Put testing depends in TEST_DEPENDS
- Remove unnecessary bsd.port.options.mk inclusions
- Remove checks for Perl versions that no longer exist in the ports tree
- Sort plists, some of which were so jumbled that I have to assume
the plist was randomized before committing
A lot of the plist changes in this commit are moving PERL5_MAN3 after
SITE_PERL. It's repo churn now, but it makes updating the ports later
far easier.

Change the way Perl modules are installed, update the default Perl to 5.18.
Before, we had:
site_perl : lib/perl5/site_perl/5.18
site_perl/perl_arch : lib/perl5/site_perl/5.18/mach
perl_man3 : lib/perl5/5.18/man/man3
Now we have:
site_perl : lib/perl5/site_perl
site_arch : lib/perl5/site_perl/mach/5.18
perl_man3 : lib/perl5/site_perl/man/man3
Modules without any .so will be installed at the same place regardless of the

Bump portrevision due to upgrade of devel/gettext.
The affected ports are the ones with gettext as a run-dependency
according to ports/INDEX-7 (5007 of them) and the ones with USE_GETTEXT
in Makefile (29 of them).

search.cpan.org redirect reduction canonicalization project, pass 2:
Refer to all modules using their /dist/Foo/ path instead of via
the mishmash of old author path, new author path, module documentation,
etc.
This pass brought to you by loving, painstaking hand editing.

Conditionalise dependencies on databases/p5-DBI: for perl
5.005_03 use databases/p5-DBI-137 as newer versions do not
support the old perl.
Note that for some port, I merely removed the explicit
dependency as they already have implicit dependencies
via other ports.

gettext upgrade uber-patch (stage 3)
- switch devel/gettext (0.11.1) on, installing full package
- flip devel/gettext-old (0.10.35) to installing only static binaries
with a "-old" suffix -- gettext-old will have its deorbit burn
sequence initiated just after 4.6-RELEASE
- fix up ports for the new world order
